A rather unsettling array of bugs have been found in Ptm B-step RTL in the days immediately after the scheduled freeze. Some bugs are associated with late fixes, but at least two problems with coherence have been there all along (one was found as a result of a Tulsa bug, one was found by inspection). The problems are in the rather complicated area of conflicts, generally associated with writebacks. We've seen a number of problems here, confirming the validation precept that "bugs are social creatures (living in groups)."
